Little word of warning about WhatsApp, my daughter changed network and her number, rather than deleting herself from the family group chat she just added her new number, we have now found out that number has been reissued and we found a stranger on our chat who was able to read everything, can’t delete them as they have become admin on it,contacted WhatsApp with no reply so had to delete the chat but it had lots of pictures on and videos which some are now lost
